Guidelines for the Adminstration of Drugs via Enteral Feeding Tubes

Guidelines for the administration of drugs via enteral feeding tubes

Enteral Parenteral Nutrition Support Committee

Midlands Regional Hospital at Tullamore (2009)

Printing sponsored by Nutricia Medical

Purpose

This guideline aims to improve pharmaceutical care of patients receiving nutrition through enteral feeding tubes (nasogastric, nasoduodenal, nasojejunal, gastrostomy/PEG, jejunostomy) by ensuring that drugs are administered in the safest and most effective manner.

ScopeThis guideline applies to all nursing and medical staff caring for patients who are to receive drugs via enteral feeding tubes. It also applies to pharmacists and dieticians who may be advising the above staff.

DisclaimerThe information in this book is intended as a guide to the administration of medication via enteral feeding tubes. Such administration is usually outside the product licence. No liability is accepted for any injury, loss or damage, however caused.

Cautionary NoticePLEASE NOTE THAT THE CORRECT ADMINISTRATION OF DRUGS VIA ENTERAL FEEDING TUBES MAY INCLUDE A SIGNIFICANT VOLUME OF WATER. IF PATIENTS RECEIVING ENTERAL FEEDING ARE FLUID RESTRICTED OR ARE AT RISK OF COMPLICATIONS FROM EXCESSIVE FLUID INTAKE PLEASE REFER TO THE MEDICAL/SURGICAL TEAM BEFORE FOLLOWING THE PROCEDURES OUTLINED IN THIS GUIDE.

Definitions and Abbreviations

Tablet: A compressed solid oral dosage form.

Capsule: A gelatin shell which may contain the active drug inside as a dry powder, dissolved in a liquid or as microscopic pellets.

Modified release: Tablets or capsules where the drug is specially formulated to be released over an extended time period. Product names will normally have one of the following suffixes: CR (controlled release), LA (long acting), SR (slow release), XL (extra long), Retard, Slow, DUO, Once Weekly, MR (modified release), Chrono, or similar abbreviation.

Incompatibility: When two drugs are mixed together in solution, one may affect the dissolution of another and possibly form a complex.

Enteral tube feeding: The delivery of nutrients via a feeding tube in patients who cannot receive adequate nutrition by oral means.

Choice of Drug

The medical team should review the drug therapy of every patient who is commencing on enteral feeding. Drugs, which are considered not to be essential in the short-term, can be withheld if appropriate.

Choice of Route of Administration

An alternative route to the enteral feeding route should be used to give the drug if appropriate. This may require a change to a different drug.

Choice of Drug Formulation

(a) Drugs that are in a Liquid Form:

If available, these are preferable for administration via enteral tubes. These include syrups, linctus’, elixirs, suspensions, solutions and dispersible, effervescent or soluble tablets.

(b) Drugs that are in a Solid Form:

(1) Uncoated Tablets: These may be crushed with care at the bedside and administered immediately (see section on “Precautions Before and After Administering” below). Do not mix powders. Always wear gloves.

(2) Coated Tablets: Do not crush enteric coated (EC), sugar coated (hard shiny appearance) or modified release (MR) tablets. Certain drugs, listed in Table 1 of this guideline require special attention. Consult a pharmacist for advice and advise the prescribing team.

For patients on fluid restriction please see the cautionary notice before proceeding.

(3) Capsules:

Hard gelatin capsules can be opened and the contents given via NG tube, provided that they are not modified release capsules (see section on “Precautions Before and After Administering” below). Soft gelatin capsules can be punctured with a wide bore needle and the liquid withdrawn and given by syringe into the enteral tube.

(4) Cytotoxic drugs and hormones should never be crushed

Drug-Feed Interactions

As a general rule of thumb, drugs which should be given on an empty stomach should not be given at the same time as enteral feed. Feed should be stopped for 1-2 hours before and 1-2 hours after such drugs are administered. Certain drugs, listed in Table 3 of this guideline require special attention.

Precautions Before and After Administering

• Each drug should be dissolved or dispersed in 20-30mls of sterile water.

• To prevent blockage of the enteral feeding tube:

• 20-30mls of sterile water (or more if recommended by the dietitian on the enteral feeding regime) should be administered before any drugs are given.

• 5-10mls should be given between each drug.

• 20-30mls of sterile water (or more if recommended by dietitian on enteral feeding regime) should be given after administration of the drugs.

• Requests to pharmacy for “clog zappers” may indicate the need for a member of the pharmacy team to review the patient’s medications.

• This fluid should be taken into account in any fluid balance calculations for patients on restricted fluid intake or at risk of complications from excessive fluid intake. Consult the medical or surgical team.

Phenytoin suspension and tablets are not equivalent: 90mg/15ml Epanutin® suspension (phenytoin base) = 100mg tabs/capsules (phenytoin sodium). Phenytoin absorption may decrease by up to 75% when administered with enteral feed. The feed should be stopped for 2 hrs before and after administration of phenytoin.
